The Rexroth KWD-035-FNS-C1-H-1 (material no. R165131321) is a genuine Bosch Rexroth ball runner block: ball runner block, FNS, size 35, steel CS, accuracy high, low preload, without ball chain.
A runner block replaces a worn or damaged carriage on a machine axis; matching size, length, preload and accuracy keeps the axis behaviour the same.

Compatibility and replacement
Order with the 10-character material number R165131321; in Rexroth codes every character (size, format, length, preload, accuracy class and seals) changes the part, so the type code KWD-035-FNS-C1-H-1 on the nameplate should match exactly.
If the nameplate of the old part is unreadable, send us a photo of the part and the axis or machine data and we will identify the matching Rexroth material number.
Before you replace it
- Accuracy class
- Seals and lubrication
- Size
